Description

Technical Field

[0001] This utility model relates to the field of building construction equipment technology, specifically to a beam and slab support. Background Technology

[0002] A beam-slab structure is a building structure consisting of slabs and supporting beams. It primarily bears bending moments and shear forces, and is made of materials with good bending resistance, such as steel, wood, or reinforced concrete. Cast-in-place reinforced concrete beam-slab structures are commonly used, generally as horizontal members, such as floor slabs and roofs composed of beams and slabs, and can also be used as vertical members, such as gates and retaining walls. Currently, the prefabrication of beams and slabs requires specific support bases. After the prefabricated beams and slabs have cured, they need to be lifted off the support bases. To facilitate lifting, the current practice is to install an adjustable base between two sets of fixed bases. During lifting, the adjustable base is removed, allowing the slings to pass through the gap and lift the prefabricated beam. Figure 4 As shown, the adjustable base consists of an early-release bracket 3 and an adjustable plate 2. The early-release bracket consists of a top support, a support cylinder, a nut, and a screw. By rotating the nut, the relative height of the support cylinder can be adjusted, thereby adjusting the height of the adjustable plate. However, during use, due to factors such as splashing water and soaking water during daily beam and slab maintenance, the lower part of the screw will quickly corrode and rust, causing the threads between the nut and the screw to interlock and form a loose connection. This not only makes the adjustable base unstable but also makes subsequent dismantling difficult, affecting construction efficiency. Utility Model Content

[0003] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a beam and slab support base that can protect the adjustment frame, which has an active adjustment function, from the effects of splashing water or soaking water during beam and slab maintenance. This makes the adjustable base stable and easy to dismantle, facilitating beam and slab maintenance and subsequent hoisting.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a beam and slab support base, comprising two sets of fixed bases and an adjustable base disposed between the two sets of fixed bases. The fixed base consists of a fixed plate and a support foot. The adjustable base includes an adjustable plate and several adjustment frames distributed on the lower side of the adjustable plate. The adjustment frame includes a fixed block and a lifting screw. The fixed block is detachably installed on the top of the support foot. The lifting screw passes longitudinally through the fixed block and is threadedly connected to it. The top of the lifting screw abuts against the lower end of the adjustable plate.

[0005] Preferably, a U-shaped groove is provided at one end of the fixing block away from the lifting screw; the top of the support foot is at least partially embedded in the U-shaped groove.

Detailed Implementation

[0020] The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings, so that those skilled in the art can more clearly understand how to practice this utility model. Although this utility model has been described in conjunction with its preferred embodiments, these embodiments are merely illustrative and not intended to limit the scope of this utility model.

[0021] See Figure 1-3 In one embodiment of this utility model, a beam support includes: two sets of fixed bases 1 and an adjustable base disposed between the two sets of fixed bases 1. The adjustable base includes an adjustable plate and a plurality of adjustment frames 4. The plurality of adjustment frames 4 are distributed on the lower side of the adjustable plate 2 and all abut against the adjustable plate 2. The horizontal height of the adjustable plate 2 can be adjusted by adjusting the adjustment frames 4 to create a gap between the adjustable plate 2 and the beam, so as to facilitate the slings to pass through the gap and lift the precast beam.

[0022] The fixed base 1 includes a fixed plate 11 and a plurality of support legs 12, which are spaced apart. The fixed plate 11 is laid flat on the support legs 12. The support legs 12 are cut into sections of a long I-beam at a certain size. For ease of understanding, the support legs 12 include a top plate 121, a vertical plate 122 and a bottom plate 123. The fixed plate 11 is fixed to the top plate 121 at the corresponding position by welding. At the same time, in order to facilitate cooperation with the adjustable base, the top plate 121 near the adjustable base has a reserved position for installing the adjustment frame 4. It can be understood that the adjustment frame 4 is located inside the two sets of fixed bases 1.

[0023] In one embodiment, the fixed plate 11 has a downward limiting step at one end near the adjustable plate 2, while the adjustable plate 2 has upward limiting steps at both ends along its length. After the adjustable plate 2 is raised, the upper surface of the adjustable plate 2 can be aligned with the upper surface of the fixed plate 11 and kept horizontal through the cooperation between the limiting steps, so that the dimensional parameters of the beam plate after prefabrication on the support seat meet the standards.

[0024] Please see Figure 2 The adjusting frame 4 includes a fixing block 41, a lifting screw 42, a handle 43, and a fastening bolt 45. The left end of the fixing block 41 is provided with a U-shaped clamping groove. The screw of the fastening bolt 45 is threaded to the left end of the fixing block 41 and extends at least partially into the U-shaped clamping groove. The fixing block 41 can be fixedly mounted on the top plate 121 near the adjustable base by the fastening bolt 45. In practice, one end of the top plate 121 extends into the U-shaped clamping groove, and the screw of the fastening bolt 45 presses against the lower end of the top plate 121. Rotating the fastening bolt 45 can tighten the top plate 121, increasing the pressure between the top plate 121 and the fixing block 41, thus keeping the fixing block 41 fixed.

[0025] The lifting screw 42 is longitudinally and penetratingly disposed at the right end of the fixed block 41. The lifting screw 42 and the fixed block 41 are connected by threads. The handle 43 is coaxially disposed at the lower end of the lifting screw 42. In use, the top end of the lifting screw 42 abuts against the lower end of the adjustable plate 2. Rotating the handle 43 can drive the lifting screw 42 to move longitudinally, thereby changing the horizontal position of the adjustable plate 2. Since the adjusting frame 4 is fixedly disposed on the top plate 121, the height difference between the adjusting frame 4 and the bottom plate 123 is significant. In addition, the adjustable plate 2 covers the upper side of the adjusting frame 4, so that the adjusting frame 4, which plays an active adjustment function, can be protected from splashing water and water immersion during beam and slab maintenance. This makes the adjustable base stable and easy to remove, and also facilitates beam and slab maintenance and subsequent lifting.

[0026] In one embodiment, the fastening bolt 45 may not be required, and at least one end of the top plate 121 may be partially embedded in the U-shaped groove, in which case the fixing block 41 and the top plate 121 are tightly fitted.

[0027] In one embodiment, the top of the lifting screw 42 is provided with a rubber support block 44. The support block 44 can increase the contact area between the lifting screw 42 and the adjustable plate 2, making the adjustable plate 2 more stable. The outer diameter of the support block 44 and the handle plate 43 are both larger than the outer diameter of the lifting screw 42 body, so that the lifting screw 42 will not slip. Based on this, for easy assembly, the handle plate 43 can be connected to the lifting screw 42 by screws, and the axis of the screw is the same as or parallel to the axis of the lifting screw 42.

[0028] In one embodiment, an anti-slip pad may be provided in the U-shaped groove, or an anti-slip groove may be provided at the position where the fixing block 41 contacts the top plate 121 in the U-shaped groove, which can further improve the stability of the adjustment frame 4 after installation and support.

[0029] In one embodiment, see Figure 3 The adjustment frame 4 also includes a spring 46, which is sleeved on the lifting screw 42 and compressed between the fixed block 41 and the handle plate 43. The spring 46 in the compressed state has a tendency to release elastic potential energy, so that the lifting screw 42 and the fixed block 41 maintain pressure. This preload can effectively prevent the lifting screw 42 from loosening and further improve the stability of the adjustable base.

[0030] It should be noted that, in order to ensure the stability of the adjustable plate 2, the number of adjustment frames 4 can be adjusted according to the needs of the site. The adjustment frames 4 located on the same top plate are distributed along the length of the top plate.

[0031] This technical solution replaces the ground-based early-removal bracket with an adjustment frame located on top of the support foot and below the adjustable plate. The adjustment frame includes a fixed block and a lifting screw. The lifting screw runs longitudinally through the fixed block and abuts against the lower end of the adjustable plate. With this configuration, the adjustment frame, which plays an active adjustment function, can be protected from splashing water and soaking water during beam and slab maintenance. This makes the adjustable base stable and easy to remove, and also facilitates beam and slab maintenance and subsequent lifting.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
